Mapping Contiguous Z-rays at the Fracture Site. Panel A shows approximately 40 X-axis grayscale images of a rat femur fracture callus stacked as a compressed 2D image. The femur intramedullary canal and fracture lines are evident. Panel B shows where the longest, contiguous Z-rays (red) from one X-axis grayscale image mapped on the compressed 2D image. Panel C shows the relative length of the contiguous Z-rays as mapped along the Y-axis.
